Has anybody done it?
I’m a SMBC so no chance of trying naturally. I always dreamed of having two children when I was younger (and assumed I would be able to find the right partner and do the traditional marriage and kids). As it is I have one amazing DC by donor sperm that I had on my own at age 41. My DD is now 3 and as she is growing more independent and we meet more and more of her peers at groups/nursery who have siblings, I’ve started to long again for a second child. So just before I turned 44 I transferred my last frozen embryo from the IVF round that gave me my DD- but it sadly ended in an early miscarriage.
If I had a partner I’d try again naturally without hesitation, but I don’t know if I am being selfish trying for a sibling for her at my advanced age with IVF. I was successful first time with her (beat the approx 28% odds I’d been given), but this time I only apparently have about an 8% chance and I will only be able to do the one round again, as there is only 1 vial of sperm left from her donor.
The one IVF round will also take a lot of my savings - so although I am mortgage free, have a steady job/good maternity leave etc, it will mean fewer extra “treats” for her like holidays etc for a while. And although I would do all the pre-natal tests if I got lucky a second time, I understand they aren’t fool- proof and that there is a higher risk of disability for children born of older mothers; so is it worth the risk of a disabled sibling, as that wouldn’t be fair on DD once I’m gone…
But my DD has no other family apart from myself, my parents and my older sibling (she is the only grandchild), so although DD is happy as she is and isn’t asking for a sibling now, she might really appreciate having one as the rest of her family gets older; as well as me wanting another child for myself.
YABU- the chance of success is tiny, spend your time and money on the child you are already very lucky to have.
YANBU- you don’t know unless you try and there are risks for everything.
